Forgery-Resistant Range Queries via Multi-Client Order-Revealing Encryption
Summary
Researchers discovered that two widely-used encryption schemes for secure database searches (m-ORE and om-ORE, which allow multiple parties to query encrypted data without revealing the queries or data) can be attacked by a malicious client and server working together to insert fake records into the database. The team developed a new scheme called MORES that fixes this vulnerability while also making searches about one-third faster and more efficient than the older schemes.
Solution / Mitigation
The source proposes MORES, described as 'the first multi-client ORE scheme that preserves range-query functionality while provably resisting arbitrarily malicious participants.' The text indicates MORES can serve as 'an immediate drop-in replacement for encrypted-database systems that demand both efficiency and robustness in adversarial environments,' but does not provide implementation details, version numbers, or step-by-step deployment instructions.
